Should childfree people receive tax credits for being responsible in not procreating and adding to the burden children place on society?

No but there needs to be a recognition that humans do not HAVE to create children and families in order to be accepted as 'normal'. Heck I have kids (all awesome humans) and I'm anything but 'normal' being that apparently I have ASD and am apparently neuro-divergent so don't do social stuff, friends, dating, relationships very well. But I've never asked for help to deal with being a dad.
